Unfortunately, some of the most rabid libs I know are Catholic.
Some things never change.
I have never known anyone more devout Catholic than my parents.
I remember well in 1972 when George McGovern ran against Richard Nixon, I was embarrassed because my parents had erected a 4'x8' McGovern campaign sign with his picture on it on the garage door of our family home. I knew Nixon wasn't well liked by some but I also knew George McGovern was a raging liberal kook. Good times.
